The first Leatherman folding knives were introduced in late 2005. Since then, 57 models have been launched, and a whopping 49 retired (many after just a couple years). It leaves just eight current models. There have been nine series of knives (seven completely retired), with models in a wide range of body types (and often, confusing naming systems).

Leatherman currently sells two types of folding knives. The Free K and T series are similar to one handle from the large Free P4 multi-tool, while the Skeletool KB and KBX are like one handle from a Skeletool. It must cut down on manufacturing costs to use the same parts!
